DETAILED DESCRIPTION

Illustrative embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. These embodiments are provided to understand the present disclosure more thoroughly and to fully convey the scope of the present disclosure to a person skilled in the art. Although illustrative embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments illustrated herein.

Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulation environment and makes users immerse in this environment. Virtual reality technology uses the data from real life to generate electronic signals by computer technology, combines them with various output devices to transform them into phenomena that people can perceive. These phenomena may be real objects in reality, or objects that cannot be seen by our flesh eyes but are expressed through three-dimensional models.

The virtual reality equipment in the present disclosure may refer to VR glasses. VR glasses use the head mounted display device to isolate people's vision and hearing from the outside world and guide the user to produce a feeling of being in the virtual environment. Its display principle is that the screens for left and right eyes display the images for the left and right eyes respectively, and a three-dimensional feeling is generated in the mind after the human eyes acquire these different information. For convenience of description, the present disclosure will be described below by taking VR glasses as a specific application example of the virtual reality equipment.

FIG. 1 shows a schematic flowchart of a local perspective method of a virtual reality equipment according to an embodiment of the present disclosure. Referring to FIG. 1 , the local perspective method of the virtual reality equipment according to an embodiment of the present disclosure comprises the following steps S110 to S130.

In step S110, a user's hand action is identified.

In the local perspective display of the virtual reality equipment, a user's hand action may be identified firstly. As shown in FIG. 2 , generally, the conventional VR glasses are equipped with a binocular camera at the external front end of the glasses, which is used to collect the external environment information and capture the user's posture and motion information, such as hand action information. In the conventional virtual reality application scenarios, computer vision technology is usually used for hand action identification. The results of hand action identification are often used for user interface operation based on the hand action, or some hand sensory games. In the embodiments of the present disclosure, the information collected by the camera installed in the conventional VR glasses may also be used to identify the user's hand action, so as to perform local perspective display according to the hand action.

It should be noted that, in addition to the above binocular camera for collecting hand action information, monocular camera or other types of camera may also be used. The specific type of camera can be flexibly set by a person skilled in the art according to the actual needs, which is not specifically limited here.

When using computer vision technology for hand action identification, the following methods may be used. Firstly, the hand action features and hand action model are designed, the hand action samples are used to extract the features, the hand action model is trained, and finally the hand action model is established. On this basis, a new hand action image is collected by the binocular camera and preprocessed; then, the hand action image is segmented so as to accurately extract the human hand part in the image; then, the hand action feature is extracted; finally, the input hand actions are classified and identified by using the previously established hand action model.

Of course, besides the above identification method, a person skilled in the art can also select other methods for hand action identification according to actual needs, which is not specifically limited here.

In addition, the above identification of the user's hand action can be real-time identification to facilitate timely response to the user's needs. Of course, for the purpose of saving power of the equipment, the hand action may be identified at a preset time interval. The specific frequency used to identify the hand action can be flexibly set by a person skilled in the art according to the actual needs, which is not specifically limited here.

In step S120, if the user's hand action satisfies a preset trigger action, a local perspective function of the virtual reality equipment is triggered.

After obtaining the user's hand action, it is necessary to further determine whether the user's hand action is an action to trigger the local perspective function of VR glasses. Therefore, the user's hand action identified may be matched with the preset trigger action. If the matching is successful, the local perspective function of VR glasses can be triggered at this point. The type of preset trigger action may be flexibly set by a person skilled in the art according to the actual needs, and is not specifically limited here.

It should be noted that “triggering the local perspective function of the virtual reality equipment” in this step can be understood as that only the local perspective function of VR glasses is triggered, and VR glasses have not actually entered the perspective state, that is, at present the user cannot see the real scene, and subsequent steps are needed to determine the local perspective display area in the virtual scene. Of course, it can also be understood that the VR glasses have entered the perspective state, and at present the user can see the real scene, but in order to avoid too much influence on the user's immersive experience, the local perspective display area in the virtual scene can be re-determined through subsequent steps.

In step S130, under the local perspective function, the local perspective display area in the virtual scene is determined according to the position of the user's hand action, so as to display a real scene in the local perspective display area.

When determining the local perspective display area in the virtual scene, the position of the hand action can be determined by using the user's hand action obtained in the above steps, and then the local perspective display area can be determined according to the specific position of the user's hand action. As shown in FIG. 3 , the user can see the real scene through the local perspective display area, while the user can still see the virtual scene at remaining parts other than the local perspective area.

The local perspective method of the virtual reality equipment according to the embodiments of the present disclosure can determine the range of the area to be perspectively displayed by using the user's hand action. Compared with the conventional global perspective solution, it can be applicable to more and richer use scenarios, and can greatly improve the user's use experience.

In an embodiment of the present disclosure, the preset trigger action includes a one-hand trigger action. The step of, under the local perspective function, determining the local perspective display area in the virtual scene according to the position of the user's hand action comprises: if the user's one-hand action satisfies the one-hand trigger action, determining positions of an index finger and a thumb of the user's one-hand action; and generating a circular perspective display area in the virtual scene according to the positions of the index finger and the thumb of the user's one-hand action.

In the embodiments of the present disclosure, the preset trigger action may be a one-hand trigger action. As shown in FIG. 4 which shows a schematic diagram of a one-hand trigger action, the palm of the user's one-hand is bent inward, and the thumb is opposite to the other four fingers to make an action similar to the “C” shape. In order to generate a more accurate local perspective display area later, if the user's hand action identified satisfies the above one-hand trigger action, the positions of the index finger and the thumb corresponding to the user's one-hand action may be further determined, and then according to the positions of the index finger and the thumb, a circular perspective display area as shown in FIG. 5 is formed between the index finger and the thumb of one-hand.

For example, in the scenario when the user wants to use the mobile phone or take a water cup, the real scene captured by the camera on the VR glasses will be perspectively displayed in the above circular perspective display area. The user can operate the mobile phone or pick up the water cup through the circular perspective display area, and the circular perspective display area can move with the movement of the user's hand.

In an embodiment of the present disclosure, the preset trigger action includes a two-hand trigger action. The step of, under the local perspective function, determining the local perspective display area in the virtual scene according to the position of the user's hand action comprises: if the user's two-hand action satisfies the two-hand trigger action, determining positions of two index fingers and two thumbs of the user's two-hand action; and generating a triangular perspective display area in the virtual scene according to the positions of the two index fingers and the two thumbs of the user's two-hand action.

In the embodiments of the present disclosure, the preset trigger action may also be a two-hand trigger action. As shown in FIG. 6 which shows a schematic diagram of a two-hand trigger action, the user's left thumb is in contact with the right thumb, the left index finger is in contact with the right index finger, all of them are located on a same plane, and other fingers may be bent and retracted or expanded, so that the area surrounded by the left thumb, the right thumb, the left index finger and the right index finger is a triangular area. In order to generate a more accurate local perspective display area later, if the user's two-hand action identified satisfies the above two-hand trigger action, the positions of the two index fingers and two thumbs corresponding to the user's two-hand action can be further determined, and then according to the positions of the two index fingers and two thumbs, a triangular perspective display area as shown in FIG. 7 is formed between the positions of two index fingers and two thumbs.

For example, in the scenario when the user needs to find something, perspective display may need to be performed in a larger range. The above triangular perspective display area will perspectively display the real scene captured by the camera on VR glasses. As the user's hands move towards both sides, the range of triangular perspective display area will gradually increase, so that users can find the things in time.

In an embodiment of the present disclosure, in addition to determining the local perspective display area in the virtual scene based on the two trigger actions listed above, other trigger actions may also be flexibly set according to the actual needs. For example, the user may draw a track having a defined shape in front of his/her eyes, and the area surrounded by the track can be regarded as the area where the user wants to perform perspective display. For example, if the track drawn by the user is a square track, the area surrounded by the square track can be perspectively displayed in the virtual scene formed by VR glasses.

In an embodiment of the present disclosure, in order to prevent the user from triggering the local perspective display function of VR glasses by mistake, when the user's hand action satisfies the preset trigger action, more complicated trigger conditions may be further set. For example, the duration of the user's hand trigger action identified can be counted. If a preset time threshold is exceeded, it is considered that the user wants to trigger the local perspective display function of VR glasses. Alternatively, the number of times of performing the user's hand trigger action may be counted. If it reaches a preset number of times of performing, it is considered that the user wants to trigger the local perspective display function of VR glasses. Regarding how to specifically set the trigger conditions of the local perspective function, it can be flexibly set by a person skilled in the art according to the actual situation, which will not be listed here one by one.

In an embodiment of the present disclosure, the method further comprises: determining whether the position of the user's hand action has changed; and if it has changed, updating the local perspective display area in the virtual scene according to a changed position of the user's hand action.

In the actual application scenarios, the user's hand position may change in real time. When the hand position changes greatly, if the local perspective display area is still determined according to the user's hand position before the change, it may occur that the local perspective display area cannot be fully matched with the user's hand. That is, the user may not be able to see what they want to see in the local perspective display area, or can only see part of it. Therefore, in the embodiment of the present disclosure, the position change of the user's hand action may be detected in real time. When the position change of the user's hand action has been detected, the local perspective display area may be re-determined according to the changed position of the user's hand action.

In an embodiment of the present disclosure, the method further comprises: if the user's hand action satisfies a preset turning-off action, turning off the local perspective function of the virtual reality equipment.

In the actual application scenarios, the user's demand to trigger the local perspective display function of VR glasses may be only temporary, such as temporarily answering a phone, temporarily drinking a cup of water, etc. Therefore, in order to ensure that the user can quickly return to the immersive experience of the virtual scene from the local perspective display function state, it may also be detected whether the user has made a hand action to turn off the local perspective function of VR glasses. If it is detected that the user's hand action matches the preset turning-off action, the local perspective display function of VR glasses may be turned off at this point.

As shown in FIG. 8 , which shows a schematic diagram of a preset turning-off action. The user can turn off the local perspective display function of VR glasses by making an action of clenching his hands in front of his eyes. Of course, in addition to turning-off the local perspective display area in the virtual scene based on the preset turning-off action shown in FIG. 8 , other turning-off actions can also be flexibly set according to the actual needs, which are not specifically limited here.

In an embodiment of the present disclosure, similar to the trigger conditions of the local perspective display function, in order to prevent the user from turning-off the local perspective display function by mistake, more complicated turning-off conditions may be further set when the user's hand action satisfies the preset turning-off action. For example, the duration of the user's hand turning-off action identified can be counted. If a preset time threshold is exceeded, it is considered that the user wants to turn off the local perspective display function of VR glasses. Alternatively, the number of times of performing the user's hand turning-off action may be counted. If it reaches a preset number of times of performing, it is considered that the user wants to turn off the local perspective display function of VR glasses. Regarding how to specifically set the turning-off conditions of the local perspective function, it can be flexibly set by a person skilled in the art according to the actual situation, which will not be listed here one by one.
